if 3/4 of a cup of yogurt is 80 calories, how many calories are in 1/4 of a cup?
Answer:
[tex]\boxed{\textsf {One fourth cup of yogurt has 26.66 calories. }}[/tex]
Step-by-step explanation:
Given that ¾ of a cup of yogurt is 80 calories and we need to find the calories in ¼ of a cup . So here we can use unitary method to find the calories.
=> ¾ cup of yogurt has 80 calories
=> 1 cup of yogurt has 80 ÷ ¾ calories .
=> ¼ cup of yogurt has 80 × 4/3 × 1/4 calories = 26.66 calories .
★ Hence ¼ of yogurt has 26.66 calories.Write the equation of the line in fully simplified slope-intercept form.
Answer:
y = -5/6x - 2
Step-by-step explanation:
The y-intercept is -2 because that is where the line crosses the y-axis Remember that slope is rise/run (there are many other terms for slope but this is the one I will reference). Therefore, the slope from one point to the next is down 5 and over 6. Since this is a decreasing slope (down 5), your slope will be negative

Leah is creating satin bows for a wedding. From a 15-meter-long ribbon, she first cuts a piece 3 4/9 meters long. Then she cuts a piece 6 5/9 meters long from the remaining ribbon. How much ribbon does Leah have left?
Answer:
5 m
Step-by-step explanation:
Total ribbon cut :
3 4/9 + 6 5/9 =
31/9 + 59/9
= 90 /9
= 10 meters
Total Length of ribbon = 15 m
Ribbon left :
15 - 10 = 5 m

Please see the screenshot and Help ASAP thank you!!
Answer:
1) Yes
2) No
Step-by-step explanation:
Substitute the x and y values of the given points into the equation and solve. If the result is a true statement, then they are solutions.
1) First, substitute the x and y values of (1,1.5) for the x and y in the given equation. Then, solve. (You can convert 1.5 from a decimal to a fraction, making it [tex]\frac{3}{2}[/tex].)
[tex]1.5= \frac{1}{4} (1) + \frac{5}{4} \\\frac{3}{2} = \frac{1}{4} +\frac{5}{4} \\\frac{3}{2} = \frac{6}{4} \\\frac{3}{2} = \frac{3}{2}[/tex]
The result is a true statement. Thus, (1, 1.5) is a solution to the equation.
2) Do the same with the point (12,4):
[tex]4 = \frac{1}{4} (12) + \frac{5}{4} \\4 = 3 + \frac{5}{4} \\4 = \frac{12}{4} +\frac{5}{4} \\4 \neq \frac{17}{4}[/tex]
The result is a false statement. The two values are not equal. Thus, (12,4) is not a solution to the equation.

What is Right Angled Triangle?Right angled triangle are those triangle for which one of the angle is 90 degrees.
Given a right angled triangle ABC.
Given that angle C is right angle.
Side AB is the hypotenuse, AC is the base and BC is the altitude.
Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.
Using the theorem,
(AB)² = (AC)² + (BC)²
(BC)² = (AB)² - (AC)²
= 17² - 8²
= 289 - 64
= 225
BC = √225 = 15 units
Hence the side length of BC is 15 units.

The top of a ladder is placed against the side of a house. The ladder is 15ft long and the wall is 12ft high. How far from the wall will the base of the ladder be positioned if the top of the ladder meets the top of the wall.
Answer:
9ft
Step-by-step explanation:
The top of a ladder is placed against the side of a house. The ladder is 15ft long and the wall is 12ft high. How far from the wall will the base of the ladder be positioned if the top of the ladder meets the top of the wall.
We solve this question using Pythagoras Theorem
c² = a² + b²
Height of the wall = Opposite side = b = 12ft
Length of the ladder = Hypotenuse = c = 15ft
Distance between the wall and the base of the Ladder = Adjacent = a
Hence:
15² = a² + 12²
a² = 15² - 12²
a = √15² - 12²
a = √81
a = 9 ft
Therefore, the wall will be 9ft from the base of the ladder , if the top of the ladder meets the top of the wall
